I can't believe no one has posted on this yet. Its absolutely hilarious, and at the same time quite interesting that someone could hack, or engineer a link to captialize on some PR 10 links. In any case its worth checking out for a laugh or to figure out how they did it. Basically some smart fellow found a way to include a link for about 11 months in a spot on the Google Default Browser Options page. The result the linked page gained a PR9 and started selling advertising to various drug related sites. Ekk!
